BINDER-LOCK.

Specification of Letters Patent.

Patented June 30, 1908.

Application filed March 16, 1906. Serial No. 306,407.

To all whom it may concern:

Be it known that I, CHARLES DANIELS, a citizen of the United States, anda resident of the city of Atchison, in the State of Kansas, haveinvented a new and useful Im rovement in Binder-Locks; and I do hereliydeclare the following to be a full and complete description of the same.

My invention relates particularly to that class of loose leaf binders,wherein the binding I osts are attached to one cover and protrur ethrough the other cover, which cover is designed to be locked inadjusted position upon said posts.

In the drawings, Figure 1 represents my binder filled with leaves withthe front end broken away. Fig. 2 represents an elevation of my binder,showing my binder lock in section. Fig. 3 is a sectlonal plan view ofFig. 2 taken through the line 3. Fig. 4 represents the key by which mylock is operated and Fig. 5 represents a detail of my lock.

More articularly described, A and A represent t e top and bottom coversrespectively.

B represents the leaves and O C the binding posts, which are firmlyseated u on the cover A and protrude through suita le perforations c, c,in the cover A. Threaded caps O O are fitted upon the ends of the posts0. C. and are larger in diameter than the perforations c, 0, whereby thecover A when unlocked may be shifted u on the posts without slipping offof the enc s of the posts 0. C.

My lock is inclosed within a casing D which may be bound within thebinding of the covers, as shown in Fig. 1, or it may be placed outsideof the said binding as may be desired. This .casing D is closed at bothends and is perforated, see Fig. 3, so as to allow the osts O. C. toextend therethrough. Lying wit in said casing D, are s ring yokes Efitted with loops of the same s iape as the posts 0. C. but sufficientlylarger to permit the said posts to pass freely through the same, (seeFig. 3). One arm of the yoke is sha ed and designed to bear against theside of tlie said casing, while the other arm of the yoke is fitted witha socket e \(Vithin said casing D and extending longitudinally therein,lies a bar F. This bar F is fitted at the center with a perforation f,and at either end with a rounded lug f f which said lugs have slidingengagement with the sockets e e of the yokes. The )erl'oration engagesan eccentric G which is rotatably secured within the said casing D. Oneside of the said eccentric G is fitted with a countersunk squared headg, which is exposed upon the surface of the cover A, (see Fig. 1) and isdesigned to receive a key II whereby the occentric may be turned. Theaction of the eccentric upon the arm F causes it to move laterallyWithin the said casing D, and this lateral movement of the arm F, actingupon the spring yokes E. E. cause them to clamp the posts C. O.extending through them. Upon the release of the eccentric by furtheraction of the said key II, the resiliency of the said yokes E. E. causethem to release the said posts O. C. and the cover A to slide freelyupon said parts.

What I claim as my invention is 1. In a binder the combination withbinding posts, and covers, one of which is attached to said posts, andthe other is adapted to slide thereupon, of a lock consisting of acasing attached tosaid sliding cover, perforations in said casingthrough which said posts are adapted to slide, spring yokes lying Withinsaid casing and embracing said posts, one end of said yokes havingengagement with the side of the said casing, an arm lying within saidcasing and having engagement with the free ends of the said springyokes, and means for moving the said arm laterally within the saidcasing.

2. In a binder the combination with binding posts and covers, one ofwhich is attached to said posts, and the other is adapted to slidethereupon, of a lock consisting of a casing attached to said slidingcover, perforations in said casing through which said posts are adaptedto slide, spring yokes lying within said casing and embracing saidposts, one end of which yokes has engagement with the said casing, anarm lying within said casing having engagement with the free ends of thesaid yokes, and means for moving said arm laterally within the saidcasing, consisting of an eccentric 'litted within suitable perforationswithin said casing and said arm.

3. In a binder the combination with binding posts and covers one ofwhich is attached to said posts, and the other is adapted to slidethereupon, of a lock consisting of a casing attached to said slidingcover, perforations in said casing through which said posts are adaptedto slide, spring yokes lying Within said casing and embracing saidposts, I one end of said yokes having engagement With the said casing,the other or free end of each yoke being fitted with a socket, an armlying Within said casing fitted at its ends With lugs, the said lugshaving engagement With the said sockets, and means for moving said armlaterally Within said casing.

4. In a binder the combination With binding posts, and covers one ofwhich is attached to said posts, and the other is adapted to slidethereupon, of a lock consisting of a casing attached to said slidingcover, perforations in said casing through Which said posts are adaptedto slide, spring yokes lying Within said casing and embracing saidposts, one end of said yokes having engagement with the said casing, theother or free end of each yoke being fitted With a socket, an arm lyingWithin said casing fitted at its ends With lugs, the said lugs Havingengagement with the said sockets, and means for moving said armlaterally Within said casing, consisting of an eccentric fitted Withinsuitable perforations in said casing and the said arm.
